The question is what kind of range does he open from UTG? Do you expect to see worse Qx hands in his range here? Or rather is he tighter side. According his bet sizing on turn it seems that he rather has a made hand even there. While bet on flop and turn differ and it it's most likely a sign of made hand. So the question is can we see worse Qx hands here in his range to make the Call here or is he capable of 2nd barreling with a draw or maybe even worse PPs?

Although as played I don't really see from what worse you get value on river, rather be happy to get a free showdown and Check it behind.
